Abstract

A passively Q-switched mode-locked Nd: YAG laser with a reflective molybdenum disulfide (MoS₂) saturable absorber (SA) was demonstrated. The MoS₂ SA was made by spin-coating the MoS₂ nanoplates onto a home-made silver mirror. The modulation depth of the MoS₂ SA was measured to be 3.05%. We optimized the laser beam radii in the crystal and on the reflective silver mirror with MoS₂ by accurately designing the oscillator cavity. Under an incident pump power of 11 W, we got the maximum average output power as high as 1.06 W with a repetition rate of 94.72 MHz. The experimental results validated the outstanding characteristics of MoS₂ SA and its further amplification possibility in high power all-solid-state pulse lasers.
